it's .30 moa @ 100yds, i've found several gunsmith's that state their guns will do .25 or less. If a guy has full custom rifle and posts a .100 group @ 100yds i'm not shocked. If a Guy says his 40yr old 30-30 can do it then i'm calling shenanigans. If you ever watched the Outdoor Channel show Gun Nuts, they tested a Savage LRH and TC Warlord and both shot groups that was were well under .5 moa.
